Vitamin K (phytomenadione) is an essential vitamin found in kale, collard green, spinach, brussel sprouts, and broccoli. It is essential for the development of new cells as it has a major role in the clotting of blood. It is used to reverse the effects of “blood thinning” medications and to treat bleeding caused by medications. It is also used in cases of bone loss or disease as well as applied topically to remove bruises, scars as well as rosacea. It also used after surgery to speed healing.
